Forklift mounted MKT hammerOccasonially
a job comes along that requires piles to be driven at the site with limited
headroom. The job discussed here was done a few years ago by George W.
Rogers at a NYC Housing Authority power plant in Brooklyn, NY.

The job had limited storage space.
No crane was to be used and the only power equipment on the job was a 13,000
lb. capacity fork lift truck set up with a fork mounted MKT 9B3 hammer.
The piles were 8 5/8" OD by .250" wall, about 40' long. Jack Dougherty
worked with Bob MacKenna of Rogers on the piling lengths delivery method
and necessary attachments to the pile.

Piles placed through
cored holes in concrete floor

It
was determined that the first section of pile would be placed in an augured
hole two feet deep. This allows a twelve (12) foot section to be used with
just enough head room for the 8'4" hammer. The second and third sections
were ten (10) feet long and the last section was eight (8) foot long.

Bundled piles being handled with
forkliftWe
fabricated the pipe with a Rock Cross point on the bottom of the first
section. The S-1800 splice was machined out on one side so it could easily
be slipped onto the pipe and a weld was made around the splicer. The second
and third sections had a splicer installed and the last section was plain
end.

The piles were bundled and strapped
in three ton lifts to allow the pipe to be handled with the fork lift and
be easily transported into the building.
